In addition, in order to better illustrate the present invention, numerous specific details are given in the following specific embodiments. It will be understood by those skilled in the art that the present invention may be practiced without certain specific details. In some instances, means well known to those skilled in the art have not been described in detail in order not to obscure the subject matter of the present invention.

参阅图1,本发明一实施例提出一种车辆TBOX的电源管理方法,包括如下步骤:Referring to FIG. 1, an embodiment of the present invention provides a power management method for a vehicle TBOX, including the following steps:

步骤S1、整车上电时,若TBOX的系统电压处于正常电压范围,则TBOX进入全功能工作状态;若TBOX的系统电压超出正常电压范围,则TBOX进入半功能工作状态;Step S1, when the whole vehicle is powered on, if the system voltage of the TBOX is within the normal voltage range, the TBOX enters the full-function working state; if the system voltage of the TBOX exceeds the normal voltage range, the TBOX enters the semi-functional working state;

具体而言,参阅图2,当整车处于上电状态时,检测TBOX的系统电压,判断TBOX的系统电压是否处于正常电压范围,所述正常电压范围为TBOX正常工作时的电压波动范围,可以根据实际工作电压数据来预先设定其具体电压值范围。Specifically, referring to Fig. 2, when the whole vehicle is powered on, the system voltage of the TBOX is detected to determine whether the system voltage of the TBOX is in the normal voltage range. The normal voltage range is the voltage fluctuation range when the TBOX is working normally. The specific voltage value range is preset according to the actual working voltage data.

其中,所述全功能工作状态包括:CAN使能,移动通信模块使能,后备电池充电使能,其他外设接口使能,车联网全功能使能,OTA使能;Wherein, the full-function working state includes: CAN enable, mobile communication module enable, backup battery charging enable, other peripheral interface enable, vehicle networking full-function enable, OTA enable;

其中,所述半功能工作状态包括:CAN使能,移动通信模块使能,后备电池充电使能,仅部分外设接口使能,车联网部分功能使能,OTA不使能。The semi-functional working state includes: CAN enable, mobile communication module enable, backup battery charging enable, only some peripheral interfaces are enabled, some car networking functions are enabled, and OTA is disabled.

步骤S21、当TBOX处于全功能工作状态时,TBOX接收OTA服务器下发的新的OTA升级任务通知,并根据所述通知判定本地是否存在未完成的升级任务,若是,则TBOX不执行所述通知所对应的新的OTA升级任务;若否,则TBOX进入本地模式以执行所述通知所对应的新的OTA升级任务;并且,TBOX进入网络模式以维持CAN网络处于唤醒状态;Step S21, when the TBOX is in a fully functional working state, the TBOX receives the notification of a new OTA upgrade task issued by the OTA server, and determines whether there is an unfinished upgrade task locally according to the notification, and if so, the TBOX does not execute the notification The corresponding new OTA upgrade task; if not, the TBOX enters the local mode to execute the new OTA upgrade task corresponding to the notification; and the TBOX enters the network mode to maintain the CAN network in an awake state;

具体而言,参阅图3,本实施例中当且仅当TBOX处于全功能工作状态时,OTA升级功能才使能,此时TBOX会加载OTA组件,OTA组件用于接收OTA服务器下发的新的OTA升级任务通知,并根据所述通知判定本地是否存在未完成的升级任务,若是,则TBOX不执行所述通知所对应的新的OTA升级任务;若否,则TBOX进入本地模式以执行所述通知所对应的新的OTA升级任务;并且,由于OTA升级是通过CAN网络对目标ECU的软件进行刷新,因此,TBOX还需进入网络模式以维持CAN网络处于唤醒状态。Specifically, referring to FIG. 3 , in this embodiment, the OTA upgrade function is enabled only when the TBOX is in a fully functional working state. At this time, the TBOX will load the OTA component, and the OTA component is used to receive new updates from the OTA server. OTA upgrade task notification, and determine whether there is an unfinished upgrade task locally according to the notification, if so, the TBOX does not execute the new OTA upgrade task corresponding to the notification; if not, the TBOX enters the local mode to execute the The new OTA upgrade task corresponding to the notification; and, since the OTA upgrade is to refresh the software of the target ECU through the CAN network, the TBOX also needs to enter the network mode to keep the CAN network in an awake state.

其中,当OTA服务器部署了升级任务,或本地存在升级任务时,TBOX与OTA服务器完成安全认证后,OTA可以与OTA服务器进行正常的通信。OTA服务器不可因为后台部署了新的OTA任务主动唤醒TBOX以寻求进行OTA升级通信。OTA升级任务采取串行的工作方式,当T-Box接收到新的升级任务通知时,需要检查本地是否还有未完成的升级任务。升级任务的完成条件只有升级完成和任务过期两种情况。如果本地存在未完成的升级任务,则新的升级任务不能开始。本步骤将根据任务属性触发升级任务。Among them, when the OTA server deploys an upgrade task, or there is an upgrade task locally, after the TBOX and the OTA server complete the security authentication, the OTA can communicate with the OTA server normally. The OTA server cannot actively wake up the TBOX to seek OTA upgrade communication because a new OTA task is deployed in the background. The OTA upgrade task adopts a serial working method. When the T-Box receives a new upgrade task notification, it needs to check whether there are any unfinished upgrade tasks locally. There are only two conditions for the completion of an upgrade task: the upgrade is completed and the task expires. If there are unfinished upgrade tasks locally, a new upgrade task cannot be started. This step will trigger the upgrade task based on the task properties.

步骤S22、当TBOX处于半功能工作状态时,TBOX停止接收OTA服务器下发的新的OTA升级任务通知;Step S22, when the TBOX is in a semi-functional working state, the TBOX stops receiving the new OTA upgrade task notification issued by the OTA server;

具体而言当TBOX处于半功能工作状态时,OTA不使能,TBOX不加载OTA组件,因此停止接收OTA服务器下发的新的OTA升级任务通知。Specifically, when the TBOX is in a semi-functional working state, the OTA is not enabled, and the TBOX does not load the OTA components, so it stops receiving notifications of new OTA upgrade tasks sent by the OTA server.

步骤S3、整车下电时,若整车满足预设的休眠条件,则TBOX退出本地模式和网络模式,并执行休眠流程。Step S3, when the whole vehicle is powered off, if the whole vehicle satisfies the preset sleep conditions, the TBOX exits the local mode and the network mode, and executes the sleep process.

具体而言,本实施例中OTA组件限定在TBOX全功能状态下运行,当TBOX处于休眠状态下或系统电压不正常时,OTA不使能。非OTA模式下OTA组件收到TBOX休眠请求后,需马上进行数据保存和退出工作。全功能状态切换至休眠状态时除了要判断休眠条件是否满足外,还需要判断OTA模式是否已退出。Specifically, in this embodiment, the OTA component is limited to run in a fully functional state of the TBOX. When the TBOX is in a dormant state or the system voltage is abnormal, the OTA is not enabled. In non-OTA mode, after the OTA component receives the TBOX hibernation request, it needs to save and exit the data immediately. When switching from the full-function state to the sleep state, in addition to judging whether the sleep condition is satisfied, it is also necessary to judge whether the OTA mode has been exited.

本实施例在整车处于下电状态,整车网络满足休眠条件后,通过网络模式和本地模式退出机制,不管TBOX的用于执行OTA升级任务的OTA组件和OTA升级任务是否处于异常状态,确保TBOX最终执行CAN网络休眠和终端休眠流程,从而确保OTA升级流程执行后整车和TBOX终端电源管理的安全性。In this embodiment, after the entire vehicle is powered off and the vehicle network meets the hibernation condition, the network mode and local mode exit mechanisms are used, regardless of whether the OTA components and OTA upgrade tasks of the TBOX used to perform the OTA upgrade task are in an abnormal state, ensuring that TBOX finally executes the CAN network hibernation and terminal hibernation process, so as to ensure the safety of vehicle and TBOX terminal power management after the OTA upgrade process is executed.

基于以上描述可知,本实施例方法应用于基于TBOX实现ECU的OTA升级的车辆,能够对该类型车辆的TBOX电源进行合理管理,确保OTA升级流程执行后整车和TBOX终端进入休眠状态,避免出现不休眠的车辆网络或终端而导致车辆亏电的现象或其产生其他不安全的影响。Based on the above description, it can be seen that the method in this embodiment is applied to a vehicle that implements OTA upgrade of ECU based on TBOX, and can reasonably manage the TBOX power supply of this type of vehicle to ensure that the vehicle and the TBOX terminal enter the sleep state after the OTA upgrade process is executed, avoiding the occurrence of The phenomenon of vehicle power loss caused by the non-sleep vehicle network or terminal or other unsafe effects.

在一些实施例中,所述执行所述通知所对应的新的OTA升级任务,包括:In some embodiments, the performing the new OTA upgrade task corresponding to the notification includes:

步骤a1、TBOX根据所述通知从所述OTA服务器处下载进行升级任务的软件升级包,并且,在下载过程中,TBOX正常执行车联网功能;Step a1, the TBOX downloads the software upgrade package for the upgrade task from the OTA server according to the notification, and during the downloading process, the TBOX normally performs the function of the Internet of Vehicles;

具体而言,TBOX在收到OTA服务器升级包下载通知后,将获取该次待升级任务的相关属性,包括:任务ID、升级概述、预计更新所需时间、升级策略、升级类型、目标ECU、目标版本等。然后进行升级任务的软件升级包下载。其中,升级包下载的步骤不影响TBOX车联网功能的正常执行,升级包下载应支持文件的断点续传。升级包下载后将进行升级包校验,通过后T-Box将根据任务属性决定下一步行动。Specifically, after receiving the upgrade package download notification from the OTA server, TBOX will obtain the relevant attributes of the task to be upgraded, including: task ID, upgrade overview, estimated time required for the upgrade, upgrade strategy, upgrade type, target ECU, target version, etc. Then download the software upgrade package of the upgrade task. Among them, the steps of downloading the upgrade package do not affect the normal execution of the TBOX Internet of Vehicles function, and the download of the upgrade package should support the breakpoint resuming of the file. After the upgrade package is downloaded, the upgrade package will be verified. After passing, the T-Box will decide the next action according to the task attribute.

步骤a2、在完成软件升级包的下载之后,TBOX获取车辆当前状态信息,并根据所述车辆当前状态信息判定是否满足升级条件,若满足,则TBOX请求整车进入OTA模式,并在整车响应所述请求进入所述OTA模式时,TBOX继续执行当前未完成的车联网功能后,停止本地运行的车联网功能,根据所述软件升级包执行新的OTA升级任务,以对目标ECU进行刷新;并且,TBOX停止响应所述OTA服务器下发的任一其它指令。Step a2: After completing the download of the software upgrade package, TBOX obtains the current state information of the vehicle, and determines whether the upgrade conditions are met according to the current state information of the vehicle. If so, TBOX requests the whole vehicle to enter the OTA mode, and responds when the whole vehicle is completed. When the request enters the OTA mode, after the TBOX continues to perform the currently unfinished IoV function, it stops the locally running IoV function, and executes a new OTA upgrade task according to the software upgrade package to refresh the target ECU; And, the TBOX stops responding to any other instruction sent by the OTA server.

具体而言,在执行升级任务前,需要进行升级环境准备工作,检测车辆升级条件是否满足包括:钥匙开关状态、车速为零、档位为驻车状态、蓄电池剩余电量充足/蓄电池电压正常、新能源车辆处于非充电状态、以及电机/发动机处于非运行状态。当进入OTA模式后,整车功能受限,而TBOX需要执行完现有的车联网功能,并拒绝执行任何云端新下发的功能以及停止本地运行的车联网功能。Specifically, before performing the upgrade task, it is necessary to prepare the upgrade environment to check whether the upgrade conditions of the vehicle are satisfied, including: key switch state, vehicle speed zero, gear position in park state, sufficient remaining battery power/normal battery voltage, new The energy vehicle is not charging, and the motor/engine is not running. When entering the OTA mode, the vehicle functions are limited, and the TBOX needs to complete the existing IoV functions, and refuses to execute any functions newly issued by the cloud and stop the local operation of IoV functions.

在升级环境准备就绪后,OTA组件将把ECU软件文件传输到MCU侧,文件传输完后,MCU侧进行文件完整性二次校验,校验通过后通知OTA组件ECU软件传输完成。OTA组件通知MCU可以开始软件刷新后,TBOX首先使目标ECU所处CAN网络停止所有应用报文的发送,避免刷新升级过程中影响刷报文通信,然后按照主机厂的诊断刷新规范对目标ECU进行目标软件版本刷新升级。若中途刷新失败,TBOX将发起刷新重试,最多两次。同样的,本步骤需要拒绝执行任何云端新下发的功能以及停止本地运行的车联网功能。此外本步骤整个过程中TBOX必须维持在全功能工作状态,维持CAN网络处于唤醒状态。After the upgrade environment is ready, the OTA component will transfer the ECU software file to the MCU side. After the file is transferred, the MCU side will perform a secondary verification of the file integrity. After the verification is passed, the OTA component will be notified of the completion of the ECU software transfer. After the OTA component informs the MCU that the software refresh can be started, the TBOX first stops the sending of all application messages on the CAN network where the target ECU is located, so as to avoid the communication of refresh messages during the refresh and upgrade process. The target software version is refreshed and upgraded. If the refresh fails in the middle, TBOX will initiate refresh retry, up to two times. Similarly, in this step, it is necessary to refuse to execute any functions newly issued by the cloud and stop the locally running IoV functions. In addition, the TBOX must be maintained in a fully functional working state during the entire process of this step, and the CAN network must be kept in a awake state.

在一些实施例中,所述执行所述通知所对应的新的OTA升级任务,包括:In some embodiments, the performing the new OTA upgrade task corresponding to the notification includes:

步骤b、当TBOX根据ECU的软件版本号确定对目标ECU刷新成功之后,TBOX请求整车退出OTA模式,并在整车响应所述请求进入所述OTA模式时,TBOX结束当前升级任务,恢复运行车联网功能,并响应所述OTA服务器下发的新的指令。Step b. After the TBOX determines that the target ECU is successfully refreshed according to the software version number of the ECU, the TBOX requests the vehicle to exit the OTA mode, and when the vehicle enters the OTA mode in response to the request, the TBOX ends the current upgrade task and resumes operation. Internet of Vehicles function, and respond to new instructions issued by the OTA server.

在一些实施例中,所述TBOX请求整车进入OTA模式,包括:In some embodiments, the TBOX requests the entire vehicle to enter the OTA mode, including:

步骤c、TBOX向车辆的中央网关发送进入OTA模式的第一请求信息,所述请求信息用于中央网关生成进入OTA模式的模式控制信号,并将所述模式控制信号广播至整车其他功能单元以使得整车进入OTA模式。In step c, the TBOX sends the first request information for entering the OTA mode to the central gateway of the vehicle, and the request information is used by the central gateway to generate a mode control signal for entering the OTA mode, and broadcast the mode control signal to other functional units of the vehicle In order to make the vehicle enter OTA mode.

具体而言,步骤中TBOX与中央网关完成安全认证,请求整车进入OTA升级模式,然后由中央网关完成整车OTA模式广播和进入步骤。Specifically, in the step, the TBOX and the central gateway complete the security authentication, request the whole vehicle to enter the OTA upgrade mode, and then the central gateway completes the whole vehicle OTA mode broadcast and entry steps.

在一些实施例中,所述TBOX请求整车退出OTA模式,包括:In some embodiments, the TBOX requests the vehicle to exit the OTA mode, including:

步骤d、TBOX向车辆的中央网关发送退出OTA模式的第二请求信息,检测中央网关广播的模式控制信号,并根据检测到的模式控制信号确定是否结束当前升级任务;其中:若检测到的模式控制信号为退出OTA模式,则结束当前升级任务;若检测到的模式控制信号为进入OTA模式,则重新向中央网关发送退出OTA模式的第二请求信息,重新检测中央网关广播的模式控制信号,并根据重新检测到的模式控制信号确定是否结束当前升级任务;In step d, the TBOX sends the second request information for exiting the OTA mode to the central gateway of the vehicle, detects the mode control signal broadcast by the central gateway, and determines whether to end the current upgrade task according to the detected mode control signal; wherein: if the detected mode If the control signal is to exit the OTA mode, the current upgrade task is ended; if the detected mode control signal is to enter the OTA mode, the second request information for exiting the OTA mode is re-sent to the central gateway, and the mode control signal broadcast by the central gateway is re-detected. and determine whether to end the current upgrade task according to the re-detected mode control signal;

其中,所述第二请求信息用于中央网关生成退出OTA模式的模式控制信号,并将所述退出OTA模式的模式控制信号广播至整车其他功能单元以使得整车退出OTA模式。The second request information is used by the central gateway to generate a mode control signal for exiting the OTA mode, and broadcast the mode control signal for exiting the OTA mode to other functional units of the vehicle to make the vehicle exit the OTA mode.

具体而言,在TBOX确认刷新完成后,TBOX向车辆的中央网关发送退出OTA模式请求,即第二请求信息,并在第二请求信息发出后的3秒内检测所述中央网关广播的模式控制信号。若在3s内未检测到正常退出,则重新发起,尝试次数最多3次,最后无论正确退出与否,均结束升级任务。Specifically, after the TBOX confirms that the refresh is completed, the TBOX sends a request to exit the OTA mode, that is, the second request message, to the central gateway of the vehicle, and detects the mode control broadcast by the central gateway within 3 seconds after the second request message is sent. Signal. If no normal exit is detected within 3s, it will be restarted, and the number of attempts is at most 3 times. Finally, the upgrade task will be ended regardless of whether the exit is correct or not.

在一些实施例中,所述执行所述通知所对应的新的OTA升级任务,包括:In some embodiments, the performing the new OTA upgrade task corresponding to the notification includes:

步骤e、当TBOX根据ECU的软件版本号确定对目标ECU刷新成功或刷新失败之后,TBOX将升级任务的升级结果上报至所述OTA服务器;并且,在将升级任务的升级结果上报至所述OTA服务器过程中,若TBOX执行休眠流程,则放弃当前升级结果的上报,并在车辆的下个点火循环过程中重新上报该升级结果。Step e. After the TBOX determines that the target ECU has been successfully refreshed or failed to be refreshed according to the software version number of the ECU, the TBOX reports the upgrade result of the upgrade task to the OTA server; and, after reporting the upgrade result of the upgrade task to the OTA During the server process, if the TBOX executes the hibernation process, the report of the current upgrade result will be abandoned, and the upgrade result will be re-reported during the next ignition cycle of the vehicle.

具体而言,在刷新过程OTA组件可保持与服务器正常通信,周期性上报升级进度。刷新完成后,在TBOX执行休眠流程前,TBOX可以通过回读目标ECU软件版本号来确认本次升级任务是否完成,并上报最终升级状态。若休眠前未完成升级结果的上报,则放弃本次升级结果上报,待下个点火循环在伺机上报。Specifically, during the refresh process, the OTA component can maintain normal communication with the server, and periodically report the upgrade progress. After the refresh is completed, before the TBOX performs the hibernation process, the TBOX can confirm whether the upgrade task is completed by reading back the software version number of the target ECU, and report the final upgrade status. If the report of the upgrade result is not completed before hibernation, the report of the upgrade result will be abandoned, and the report will be waited for in the next ignition cycle.

在一些实施例中,所述执行所述通知所对应的新的OTA升级任务,包括:In some embodiments, the performing the new OTA upgrade task corresponding to the notification includes:

步骤f、若开始刷新目标ECU之后,在第一预设时间内未能够刷新成功目标ECU的软件,则TBOX请求整车退出OTA模式,并在整车响应所述请求进入所述OTA模式时,TBOX结束当前升级任务,恢复运行车联网功能,并响应所述OTA服务器下发的新的指令。Step f. If the software of the target ECU cannot be successfully refreshed within the first preset time after starting to refresh the target ECU, the TBOX requests the vehicle to exit the OTA mode, and when the vehicle enters the OTA mode in response to the request, The TBOX ends the current upgrade task, resumes the operation of the Internet of Vehicles function, and responds to the new instructions issued by the OTA server.

具体而言,若在第一预设时间内(例如预计更新所需时间乘以3),未能成功刷新目标ECU,TBOX同样会向中央网关发送退出OTA模式请求。整车退出OTA模式后,整车功能和网络通信恢复正常,TBOX可自主决定执行休眠唤醒流程。Specifically, if the target ECU cannot be successfully refreshed within the first preset time (for example, the estimated time required for the update multiplied by 3), the TBOX will also send a request to exit the OTA mode to the central gateway. After the vehicle exits the OTA mode, the vehicle functions and network communication return to normal, and the TBOX can independently decide to execute the sleep-wake-up process.

在一些实施例中,所述执行所述通知所对应的新的OTA升级任务,包括:In some embodiments, the performing the new OTA upgrade task corresponding to the notification includes:

步骤g、若整车进入OTA模式之后,中央网关在第二预设时间内未接收到TBOX请求整车退出OTA模式的第二请求信息,则中央网关生成退出OTA模式的模式控制信号,并将所述模式控制信号广播至整车其他功能单元以使得整车退出OTA模式。Step g. If after the vehicle enters the OTA mode, the central gateway does not receive the second request information from the TBOX requesting the vehicle to exit the OTA mode within the second preset time, then the central gateway generates a mode control signal for exiting the OTA mode, and sends the information to the central gateway. The mode control signal is broadcast to other functional units of the vehicle to make the vehicle exit the OTA mode.

具体而言,若在约定时间内(Tmax,OTA升级及重试所需最长时间),TBOX未能发起退出OTA模式请求,中央网关最终也需要向整车广播退出OTA模式的模式控制信号。Specifically, if the TBOX fails to initiate a request to exit the OTA mode within the specified time (Tmax, the longest time required for OTA upgrade and retry), the central gateway also needs to broadcast the mode control signal to the vehicle to exit the OTA mode.

通过上述实施例的描述可知,本发明的实施例对于OTA升级方案,设计了合理的电源管理方法,考虑了如何确保OTA可独立运行不影响到用户正常车联网功能的使用,如何保障本地ECU自刷新任务可成功执行完成,如何确保OTA车端电源管理方案尤其是休眠唤醒流程合理执行等情况。通过本地模式与网络模式把车联网功能与CAN网络解耦,根据具体车联网功能按需唤醒和维持CAN网络。OTA归类到本地模式设计中,对车联网功能与和OTA功能进行协同管理,在进入OTA模式时实现互斥设计,停止执行车联网功能,保障OTA升级任务的顺利执行。在整车处于下电状态,整车网络满足休眠条件后,通过网络模式和本地模式退出机制,不管OTA组件和OTA升级任务是否处于异常状态,确保TBOX最终执行CAN网络休眠和终端休眠流程,从而确保OTA升级流程执行后整车和TBOX终端电源管理的安全性。From the description of the above embodiments, it can be seen that the embodiments of the present invention design a reasonable power management method for the OTA upgrade scheme, and consider how to ensure that the OTA can operate independently without affecting the normal use of the user's IoV function, and how to ensure that the local ECU automatically The refresh task can be successfully executed. How to ensure the reasonable implementation of the OTA vehicle-side power management scheme, especially the sleep and wake-up process. The car networking function is decoupled from the CAN network through the local mode and network mode, and the CAN network can be woken up and maintained on demand according to the specific car networking function. OTA is classified into the local mode design, and the IoV function and the OTA function are managed collaboratively. When entering the OTA mode, a mutually exclusive design is realized, and the implementation of the IoV function is stopped to ensure the smooth execution of the OTA upgrade task. After the vehicle is powered off and the vehicle network meets the hibernation conditions, the network mode and local mode exit mechanisms ensure that the TBOX finally executes the CAN network hibernation and terminal hibernation processes regardless of whether the OTA components and OTA upgrade tasks are in an abnormal state. Ensure the safety of vehicle and TBOX terminal power management after the OTA upgrade process is executed.
